Subject:
X-ray diffraction; adsorbents; adsorption; carbon dioxide; desorption; engineering; flue gas; models; nitrogen; porous media; scanning electron microscopy; silica; temperature; transmission electron microscopy
Abstract:
... A novel solid adsorbent for CO₂ capture was developed by loading pentaethylenehexamine (PEHA) on SBA-15 by a wet impregnation method. The structural properties of the adsorbents were characterized by the XRD, N₂ adsorption/desorption, TGA, SEM, and TEM techniques. The effects of PEHA loading, adsorption temperature, and height/diameter ratio of the fixed bed on the CO₂ adsorption performance were ...

Subject:
carbon dioxide; carbon monoxide; combustion; engineering; fluidized beds; fuels; inventories; oxygen; potassium; strength (mechanics); temperature; volatilization
Abstract:
... Raw ilmenite was tested as an oxygen carrier for chemical looping combustion (CLC) in a dual fluidized bed reactor for 100 h. After this 100 h test, 21 wt % of the total used raw ilmenite was impregnated with 10 wt % potassium (K). The K-impregnated ilmenite mixed with the remaining used raw ilmenite was tested in the same reactor for 40 h. During the 100 h test, raw ilmenite showed a low reductio ...

Subject:
carbon dioxide; coolers; electric power; energy; engineering; flue gas; mathematical models; temperature
Abstract:
... As a promising alternative to mitigate the emission of CO₂, cryogenic CO₂ capture techniques have been paid increasing attention. In our previous works, a novel deposition CO₂ capture process based on free piston Stirling coolers (FPSCs) has been developed. Compared to conventional cryogenic CO₂ capture approaches, FPSC was selected to provide cold energy for CO₂ deposition because of its signific ...

Subject:
alcohol dehydrogenase; boehmite; calcium alginate; carbon dioxide; chemistry; electrostatic interactions; encapsulation; engineering; fluorescence; hybridization; immobilized enzymes; yeasts
Abstract:
... A novel kind of matrix for enzyme immobilization, the boehmite/alginate hybrid beads, was fabricated under mild conditions in this study. The boehmite particles were first prepared via a mild sol–gel technology and were then entrapped into the inherent network of calcium alginate. The characterization results suggest that the hybridization between alginate and boehmite belongs to a physical blendi ...

Subject:
Cretaceous period; ash content; basins; carbon; carbon dioxide; coal; engineering; gasification; models; nitrogen; surface area; temperature
Abstract:
... Seven coal samples taken from cores drilled in the Cretaceous Mannville Group were used for investigation of coal properties and carbon dioxide (CO₂) gasification. The depths of the cores ranged between 700 and 800 m below the surface in the Western Canadian Sedimentary Basin. A new method was developed with an average heating rate of 200 K/min using CO₂ as the gasifying agent from the experiment’ ...

Subject:
carbon dioxide; carbon monoxide; catalysts; combustion; engineering; equations; hematite; hydrogen; magnesium; magnesium hydroxide; methane; spectral analysis; temperature; thermogravimetry
Abstract:
... Iron oxide (Fe₂O₃), known in its natural form as hematite, is potentially able to capture CO₂ through the chemical-looping combustion (CLC) process. Magnesium (Mg) is an effective methyl-cleaving catalyst, and as such it was combined with hematite to assess any possible enhancement to the kinetic rate of the reduction of Fe₂O₃ with methane. Therefore, in order to evaluate the effectiveness of Mg a ...

A specific experimental methodology was developed to obtain quantitative data on key components of interest present in evolved gases during TG-FTIR runs in air and nitrogen at low heating rates. Multivariate deconvolution techniques were used to id ...
